The James Webb Space Telescope has provided clues to the cause of the extremely bloated atmosphere of a Neptune-like exoplanet… more
The Webb Telescope has provided evidence of a hot rocky planet’s gas shell apparently emerging from its seething embers… more
An “astronomical twin study” has found evidence that some stars have incorporated planetary material… more
Astronomers have documented how the radiation wind from nearby star giants erodes the protoplanetary disk of a young star. This means that the building material for gas planets is lost… more
Why are there so surprisingly few exoplanets twice the size of Earth? Astronomers have now provided a possible explanation for this gap in the size distribution… more
Astronomers have succeeded in detecting the spectral signature of water vapor in the gas envelope of a nearby, potentially water-rich exoplanet… more
Astronomers have found evidence of the formation of planets and iron-containing building materials in the inner region of a circumstellar disk… more
To identify planets with potentially life-friendly oceans, one could compare the carbon dioxide levels of their atmospheres with those of their neighboring planets, say astronomers… more
How could this heavyweight emerge? Astronomers have discovered a surprisingly massive planet in close orbit around a very small star… more
A turbulent gas envelope in sight: Astronomers have discovered signs of clouds of silicate particles in the atmosphere of a “bloated” exoplanet, in addition to the signatures of water vapor and sulfur dioxide. It appears that intensive material transport in the hot gas envelope is causing this sand to settle in the high-altitude… more
